What component of the landing gear absorbs shock during landing?

The component of the landing gear that absorbs shock during landing is the strut. Struts are designed to provide a cushioning effect to manage the loads and impact forces that occur when an aircraft lands. They are typically filled with either hydraulic fluid or gas, and they work by compressing when a load is applied, which helps to dissipate the energy generated from the landing impact. This function is crucial for maintaining structural integrity and providing a smooth transition upon touchdown, allowing for better control and comfort for passengers and crew.

The other components listed do not serve as shock absorbers. Fairings are used to streamline the landing gear and improve aerodynamics but do not provide cushioning. Axles serve as pivots or support points for the wheels, allowing them to rotate but do not absorb shock directly. Wheels are essential for rolling during takeoff and landing, but they primarily support the aircraft's weight rather than absorb the shock of landing. Thus, the strut's primary role as a shock absorber makes it the correct answer.
